Hello guys.First time here.I was trying to install incompatible apps to my phone today and i started reading that i have to root my phone.So i did it and i followed exactly the directions.I rooted it,a super user icon showed normally and i followed exactly the direction i found here How to Install Incompatible Android Apps from Google Play - How-To Geek Exactly.The only things i did was to change the ro.product.model from GT S6102 to Nexus S in order to be able to install the incompatible apps.Then i cleared data and cache as it said and restarted my device.And then it won't open.When i see the samsung logo flashing then it vibrates 3 short times and then it restarts itself and then the same and the same.Until i pull off the battery.I tried to unroot it but nothing changed.Please help me guys.My cell phone is Samsung galaxy s duos.(Sorry if this place isn't the right one to post my problem)
